nncannomame AND nuniucnrme DEVICE.

This invention relates to an improved decarbomzmg and lubricating device for 1nternal combustion engines, being somewhat similar to the decarbonizer disclosed in Patcut No. 1,356,967, granted to me October 26,

The invention seeks, among other objects,

to provide a device for admitting successive small quantities of decarbonizing fluid to the cylinders of an engine for loosening any carbon or oily deposits in the cylinders while the engine is running so that the loosened carbon will be expelled from the cylinders,

and wherein the device may then be. operated to admit oil to the cylinders for lubri cating the cylinders before the ignition circuit is c'losed and the engine is set to work, .to thereby obviate abrasion, to the cylinder walls, pistons, .or piston rings.

' The invention seeks, as a further object, to provide. a device embodying a decarbonizing fluid container and an oil'contain,

vice applied.

Figure 2;is a vertical sectional view on the line 2+2 of Figure 1, looking in the direction indicated by the arrows.

Figure 3 is a detail elevation of the control knob employed.

In carrying the invention into effect, I emloy a decarbonizing fluid container or chamber 10, beside which is arranged an oil container or chamber 11 connected with the former container by a web 12. Thus, the containers comprise a singleunit and, as shown, the container 10 is considerably larger than the container 11. Both of the containers are of substantially cylindrical shape and screwed on the upper end of the container 10 is a cover 13 while a cover 14: is similarly attached to'ther-upper end of thecontainer 11. Rising from the; cover 13 is a venttube 15Tand rising from the cover 14 is a similar vent tube 16. Near their uppern ends, these tubes are turned laterally so as Application filed larch so, 1925. Serial No. 19,481.

to prevent the entrance of foreign matter through the tubes into the containers.

Screwed through the bottom of the container 10 is an axially disposed standp'ipe 17 closed at its upper end by a plug 18, and extending upwardly along said ipe at its outer side is a pair of syphon ,tu es 19, the upperends of which are turned laterally into the upper end of said pi e and ex tend through the plug'18. At t eir lower ends, the tubes 19 terminate close to the bottom of the container 10 and it is now to be observed that this container provides a liquid chamber 20 while the standpipe 17 provides a suction chamber 21 connected with the liquid chamber by the syphon tubes. Near the lower end thereof, the pipe 17 is provided with an internal web 22 and screwedthrough said web is a downwardly opening spring pressed check valve 23.

Screwed on the lower end of the standthe improved device mounted at the forward. side of the dash 29 of a conventional motor vehicle. The instrument board of the vehicle is indicated at 30 while the-intake manipipe 17 externally of the container 10, is a fold of the vehicle engine is indicated at:

31. In the present instance, I have shown the container 10 as provided at its rear side with a laterally directed stud 32 which is arranged to extend through the dash 29 and screwed: on said stud is a nut 33 rigidly connecting the device with the dash. How-.

knob is provided with a shaft 36, the adjacent section" of which is journaled through a bearing plate 37 fixed to the instrument board and, as will be observed, said shaft;

connects the knobowith the valve stem 34, suitable universal-joints 38 being interposed in the length of the shaft. Thus, the knob may be turned for rotating the valve 25;

in this connection, it is to be noted that the plate 37 is preferably providedwith an indicating arrow while the knob is provided with suitable indicia for denoting the different set positions of the valve. The device is brought intouse after the vehicle engine has been running some time so that the cylinders will be hot, and preferably when the yehicle is descending a grade, so

' that the engine may, by the momentum of the vehicle, be kept in operation with the ignition off. Under these conditions the valve 25 is turned to the position shown in Figure 2, for connecting the suction chamber 21- with the manifold 31. Accordingly, engine suction will be communicated to the suction chamber'21 so that upon the downward stroke of each of the engine pistons, a

small quantity of decarbonizing fluid-will be lifted from the chamber 20 through the tubes 19into the chamber 21, to thence flow through the pipe 39 to the manifold-and thence into one of the cylinders. Upon entering the cylinders, the' decarbonizing fluid will tend to soften any carbon deposits in the cylinders as well as tend to remove any oil residue on the cylinder walls, pistons, and

piston rings, and in feeding the decarbonizing fluid to the cylinders in successive small quantities, the greatest cumulative effect will be obtained. After all of the decarbonizi-ng fluid has been discharged into the cylinders and before the ignition is turned on, the valve 25 is turned to connect the container ll with the pipe 39 so that oil from said container will be drawn into the manifold and thence taken into the engine cylinders. Accordingly, the cylinder walls, pistons and piston rings will be again properly lubricated so that by the time the bottom of the grade is reached, the ignition circuit may be closed and the engine operated without danger of scoring or scratching thecvlinder walls, pistons and piston rings through'faulty lubrication. When the enof said web.

gine is thus set to work, the loosened carbon and oil residue will be blown out through the exhaust manifold of the engine with the result that the engine cylinders, pistons and piston rings Will be rendered comparatively clean. I accordingly provide a device which may be operated-without inconvenience to the motorist and wherein all danger of injury to the engine through the removal of lubricant fromthe engine cylindersby the decarbonizing fluid, will be avoided by the introduction of an auxiliary supply of lubricant to the cylinders. If desired, the containers 10 and 11 may be mounted at the rear side of the vehicle dash within reach of the driver when, of course, the control knob 25 will be mounted directly on the valve stem 34 and the control shaft eliminated. 4

Having thus described the invention, what 1- claim is: 1. In a decarbonizing and lubricating device, the combination of a decarbonizing fluid chamber provided at its lower end with a nipple, a lubricant chamber provided at its lower end with a nipple and connected at a point between its ends with the former chamber by a web supporting the lubricant chamber beside the fluid chamber, and a pipe extending between said nipples connecting the lubricant chamber with an outlet common to both chambers and forming a rigid brace between the lowerends of the chambers for bracing the chambers against relative movement and preventing fracture 2. Ina decarbonizing and'lubricating device, the combination of a decarbonizing fluid chamber, a lubricant chamber smaller than the former chamber and connected at a point between its ends with the fluid chamber by a web supporting the lubricant chamber in spaced parallel relation to the fluid chamber within the linesthereof, said chambers being provided at their lower ends with nipples, and a pipe extending between said nipples connecting the lubricant chamber with an outlet common to both chambers and forming a rigid brace between the lower ends of the chambers for bracing thechambers against relative movement and preventing fracture of said'web.

. In testimony whereof I aflix my signature.
